Cartridge loading

Chakster, I am experimenting with a device made by Intact Audio.  It's a prototype, one-off, not in production.  It's "based on a Nelson Pass I/V converter for current output DACs", according to Intact Audio.  It is not a phono stage per se; it is inserted into the chain between the LOMC and the input of an MM phono stage, or any phono with a 47K input resistance (I guess).  The output of the IA device drives the MM input of my Manley Steelhead, set at 50db of gain. (There is no added gain from the high level section of the Steelhead.)  No hiss or otherwise intrusive noise or hum allows me to appreciate the MC2000 for the first time. (I don't own the T2000 SUT or another SUT with similar characteristics.) 

atmasphere : You are so " curios " when posted:

""  electrical damping of an electro-mechanical transducer results in less high frequency output of that transducer.  ""

no one is questioning that ( at least not now. and is not what I asked several times here and in other threads. ).

What I asked you are true evidence of your statement about that: 

""" LIMIT TRACE....."""

wich of your words you don't understand?, that was the issue. Not any more and at least for me is clear that your statement about is totally: FALSE. That's a lie till some one prove that " limit trace .." is not false.

"" electrical damping of an electro-mechanical transducer results in less high frequency output of that transducer. ""

no one is questioning that ( at least not now. and is not what I asked several times here and in other threads. ).

So we are in agreement as seen above. That is the same as:

What I asked you are true evidence of your statement about that:

""" LIMIT TRACE....."""

IOW when the cartridge is loaded (damped) its ability to trace high frequencies is reduced because the cantilever will be stiffer. If you agree with your first post above as you say you do, then you have to agree with this also. They are the same.

atmasphere : """    is loaded (damped) its ability to trace high frequencies is reduced because the cantilever will be stiffer... """

I said " at least not now...".

For the lectrical loading could " limit trace... " it needs that the cartridge be overdamped and the cartridge designers already has all calculated for that kind of cartridge behavior never be present or even approach it. It's almost the same in tonearm designer calculations when they design the use of oil/silicon damping, they make the calculation for overdamping can't happens because overdamping limit the trace of the stylus tip ridding during play the LP.

Now I ask for numbers/value of that loading resistor to " limit trace... "  and you don't show any " numbers " about that can be corroborated.

No one wants an overdamped cartridge: electrically or mechanically, these is out of question.


This is what I posted to lewm in this same page for you can read it:


"" did you know how much " force " do you need to apply/need/ at the base of the cantilever to really impedes at the stylus tip position its free movements, a tiny movement? no?
Btw, do you know the " power forces/inertia " generated at the stylus tip when ridding the grooves at 33/45 rpm and what " force " is need it to " limit the trace " of the stylus tip to track when appliyed that force/loading at the other end of the cantilever? ..."""

Which is the force need it to broke that very high inertia generated by the friction between the groove modulations and stylus tip when the cartridge is ridding/tracking those grooves that can " limit trace HF "" ?

I don't know that answer concerning the loading resistor value to broke that inertia. We have to think that load resistance takes its effect at the cantilever base and the stylus tip is ridding at the other end/extreme of the cantilever and this makes " things " extremely complicated to that " limit trace " issue.  """


Did you read it?  because is all common sense.

So, your " limit trace ..." statement continue be false.

R.

So, your " limit trace ..." statement continue be false.

Your feculent argument is also specious. You can't have it both ways.
